Description

Technical Field

[0001] The utility model relates to the field of shock absorption of household appliances, in particular to a self - retracting shock - absorbing gasket for preventing self - sourced vibration of household appliances. Background Technique

[0002] In daily life, household appliances are an essential part. With daily use and the increase of years, some household appliances, such as wall - mounted air conditioners and floor - standing washing machines, will inevitably generate frequent vibrations due to mechanical aging, internal motor wear, etc. A large amount of noise generated by the vibrations makes people who are resting extremely disturbed.

[0003] Common methods for preventing shock and noise of household appliances are to fix the sound - generating parts with waste elastic materials, such as the connection seams between wall - mounted air conditioners and walls, or the seams between the four corners of drum washing machines and the ground. Sound is eliminated by stuffing items such as corrugated paper, table mats, old books, etc. or special cushioning materials. However, this method is not always effective. The fatigue limit of the cushioning material and the aging of the connection parts after a period of time lead to larger gaps, so the cushioning material needs to be updated after a period of time, which is very cumbersome. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and provide a self - retracting shock - absorbing gasket for preventing self - sourced vibration of household appliances, which effectively reduces the noise of household appliances and prolongs the service life of household appliances.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A self - retracting shock - absorbing gasket for preventing self - sourced vibration of household appliances, including rubber bearing platforms arranged on the left and right or front and back sides of the household appliance. The contact surface between the rubber bearing platform and the household appliance is an inclined surface or an arc surface. At the bottom of each end of the rubber bearing platform away from the household appliance, a stepped mounting hole is provided. At the top inside the mounting hole, a reciprocating source is provided. In the lower part inside the mounting hole, a spiral clamping ring is fixedly provided. Inside the spiral clamping ring, a vibrating disc is provided. Below the mounting hole, a wire - winding disc is provided. The reciprocating source and the vibrating disc, as well as the vibrating disc and the wire - winding disc, are all connected by connecting columns. At the bottom of the wire - winding disc, a ground pedal is provided. The wire - winding discs of the two rubber bearing platforms are connected by a wire. On the inner wall of the spiral clamping ring, an annular groove is provided. Along the circumferential direction of the annular groove, a plurality of wedge - shaped blocks are evenly provided on the top or bottom surface inside the annular groove. On the outer peripheral wall of the vibrating disc, a plurality of sliding blocks are evenly provided. One end of the sliding block is provided with an inclined surface adapted to the wedge - shaped block.

[0007] Preferably, a notch adapted to the wire is provided at the bottom of the end of the rubber bearing platform close to the household appliance.

[0008] Preferably, a set of alignment rivets adapted to the wire rope are provided at the bottom of the end of the rubber bearing platform close to the household appliance, and the wire rope passes through between the two alignment rivets.

[0009] Preferably, a rigid block is provided at the bottom of the rubber bearing platform.

[0010] Preferably, the reciprocating source includes a push plate piston and an air chamber cooperating with the push plate piston.

[0011] Preferably, the reciprocating source is a spring or porous rubber.

[0012] Preferably, the ground pedal is wedge-shaped.

[0013] Preferably, an anti-slip structure is provided at the bottom of the ground pedal.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The rubber bearing platforms of the present utility model are used in pairs. The rubber bearing platforms absorb the continuous vibration from the upper part and feedback it to the spiral clamping ring and the vibrating disc, causing relative synchronous vibration between the spiral clamping ring and the vibrating disc, so that the vibrating disc rotates unidirectionally, driving the wire rope take-up reel below to take up the wire rope. The wire rope connects the wire rope take-up reels of two symmetrically conjugate rubber bearing platforms, performs opposite take-up, and determines the axis alignment direction through the alignment rivets to gradually reduce lateral slip. After running for a period of time, the conjugate rubber bearing platforms successfully fit into the gaps of the vibrating machinery, stopping the vibrating noise. The present utility model converts the vibration of old household appliances into the take-up movement of high-strength wire ropes, effectively reducing the noise of household appliances, making residents feel comfortable, and reducing the continuous impact loss of household appliances, prolonging the service life of household appliances.

Specific embodiments

[0022] The following further elaborates on the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0023] Embodiment: As shown in the attached Figures 1-5 figure, the present utility model relates to a self-collecting shock-absorbing gasket for preventing self-excited vibration of household appliances, including rubber bearing platforms 1 arranged on the left and right or front and back sides of the household appliances. The contact surface of the rubber bearing platforms 1 with the household appliances is an inclined surface or an arc surface. At the bottom of each end of the rubber bearing platform 1 far from the household appliances, there is a stepped mounting hole 2. At the top inside the mounting hole 2, there is a reciprocating source 3. At the lower part inside the mounting hole 2, there is a fixed spiral clamping ring 4. Inside the spiral clamping ring 4, there is a vibrating disk 5. Below the mounting hole 2, there is a wire take-up reel 6. Both between the reciprocating source 3 and the vibrating disk 5 and between the vibrating disk 5 and the wire take-up reel 6 are connected by connecting columns. At the bottom of the wire take-up reel 6, there is a ground anchor 7. Between the wire take-up reels 6 of the two rubber bearing platforms 1, there is a wire connection. On the inner wall of the spiral clamping ring 4, there is an annular groove 41. Along the circumferential direction of the annular groove 41, a number of wedge blocks 42 are evenly arranged on the top or bottom surface inside the annular groove 41. On the outer peripheral wall of the vibrating disk 5, a number of sliding blocks 51 are evenly arranged. One end of the sliding block 51 is provided with an inclined surface 52 adapted to the wedge block 42.

[0024] Among them, the wire connection uses a high-strength wire. The reciprocating source 3 ensures that the spiral clamping ring 4 and the vibrating disk 5 can be reset to ensure that the next unit of movement can be carried out after the completion of one unit of movement, so that the system can operate successfully. The spiral clamping ring 4 provides a generalized downward ramp so that the vibrating disk 5 clamped therein can rotate continuously in one direction in a generalized manner. The wire take-up reel 6 moves together with the upper vibrating disk 5 to collect and anchor the wire (high-strength wire) in the wire take-up reel 6. The ground anchor 7 ensures the stable operation of the entire shock-absorbing gasket and ensures that the whole is fixed in a fixed position after the collection is completed. The wire (high-strength wire) causes an opposite movement when the shock-absorbing gasket on the opposite side is tightened, and shares the horizontal component force in the final structure form.

[0025] The rubber bearing platform 1 is wedge-shaped as a whole. Except for the bottom surface, the other surfaces can all adopt the form of arc surfaces to facilitate insertion into the working gap. A slot 11 is opened at the bottom surface of the rubber bearing platform 1 along the established movement direction to ensure the smooth outgoing of the wire. In the inner side of the rear half of the rubber bearing platform 1, two slot holes (mounting holes 2) are dug. The two slot holes are stacked up and down in a cake shape and are arranged with their central axes coinciding. The upper one is smaller and the lower one is larger. A reciprocating source 3 is arranged in the smaller control part at the top, and a spiral clamping ring 4 is arranged in the larger control part at the bottom. The rubber bearing platform 1 can be integrally formed to reduce hidden cracks and avoid fatigue damage under long-term vibration.

[0026] A rigid block 13 can be arranged at the lower part of the rubber bearing platform 1, which is divided into front and rear parts, so that the front inserted part and the rear vibrating part are separated. The rigid block 13 under the rubber bearing platform 1 can adopt Kevlar material to increase rigidity while reducing the flexible damage to the upper rubber bearing platform 1.

[0027] At the bottom of one end of the rubber bearing platform 1 close to the household appliance, a set of alignment rivets 12 adapted to the wire are provided. The wire passes through between the two alignment rivets 12, and the alignment rivets 12 ensure that the outgoing direction is within the vertical symmetry plane of the self-tightening shock-absorbing gasket.

[0028] The reciprocating source 3 can be composed of an air chamber 32 with good air tightness and a push plate piston 31 that closely cooperates with it. The two form an air fork structure to achieve a buffering effect. A lubricating rubber gasket can be arranged between the push plate piston 31 and the air chamber 32 to ensure good air tightness. It should be noted that the air chamber structure is one of the set structures, and the reciprocating source 3 can also adopt buffer structures such as a spring structure and a porous rubber structure.

[0029] The spiral clamping ring 4 can be composed of two circumferentially arrayed convex surface chutes up and down, presenting a hollow cylindrical shape. Each convex surface chute unit in the chute is trapezoidal, and the inclined surfaces are placed in the same direction and are arranged circumferentially along the axis of the spiral clamping ring 4 to form a complete circumferentially arrayed convex surface chute. The shapes of the two convex surface chutes up and down are congruent, and the staggered convex surface chute units are placed staggeredly corresponding to half of the circumferential angle. The minimum distance between the upper and lower chutes should be slightly larger than the maximum vertical height of the largest block in the vibrating disk 5.

[0030] The diameter of the central disk of the vibrating disk 5 is slightly larger than the central vacancy of the spiral clamping ring 4. Anchor sliding blocks 51 are fixed around the central disk. The sliding blocks 51 are trapezoidal and are placed inside the upper and lower circumferentially arrayed convex surface chutes of the spiral clamping ring 4.

[0031] The wire reel 6 is fixed at the lower part of the vibrating disk 5, and its central axis coincides with the central axis of the vibrating disk 5. The diameter of the wire reel 6 is slightly smaller than the width of the corresponding position of the rubber bearing platform 1 in the top view. The shape of the wire reel 6 is like three cake-shaped blocks stacked together. The upper and lower blocks are the same, and the middle block is slightly smaller than the other blocks, which is convenient for the wire winding work of the high-strength wire.

[0032] The ground pedal 7 is fixed to the lower part of the wire reel and is in the shape of a wedge. The bottom surface of the ground pedal 7 forms a certain angle with the bottom surface of the rubber bearing platform 1, and the direction of the angle faces the established moving direction. Anti-slip grooves can also be provided on the bottom surface of the ground pedal 7.

[0033] The utility model can be placed in two opposite sides, clamped under the opposite side lines of the collision surface of the vibrating household appliance, so that the four-corner support of the vibrating household appliance is completely fixed, and the generation of noise can be effectively reduced; by converting the vibration of the external household appliance into the rotation of the wire reel inside the utility model itself, and through the rotation to bundle the high-strength wire, the opposite shock pads are driven to approach each other, driving the upper rubber bearing platform to move inward, meeting the requirement for the thickness of the pads when the household appliance further ages and generates larger cracks in the future; it can be used for a long time after one installation, which is convenient and efficient, and has a simple structure, low cost and convenient installation.

[0034] The utility model is used in two sets at the same time to achieve the four-corner support effect, avoiding the problem that only two corners work due to inconsistent working conditions and the vibration at the ineffective side line is still obvious.

[0035] I). The embodiments for wall-mounted household appliances, especially the indoor unit of wall-mounted air conditioners, are as follows:

[0036] Wall-mounted air conditioners often use hanging plates to connect to the wall. The initial installation steps of the hanging plate are as follows: determine the preliminary position - level - drive in rivets for fixation. After fixing the hanging plate, hang the indoor unit of the air conditioner at the corresponding bayonet of the hanging plate. With daily use, the hanging plate part undergoes fatigue wear, reducing the restraint on the indoor unit. At the same time, the fan shaft inside the air conditioner undergoes fatigue wear, generating relative eccentric motion, thus resulting in the condition that the entire indoor unit of the air conditioner repeatedly impacts the corresponding position of the wall.

[0037] For this kind of working condition, first select two shock pads, fix the wire on the wire reel and pass it through the alignment rivet to ensure the correct wire-receiving direction. The shock pads in the same group are placed vertically up and down naturally, so that the wedge-shaped small head of the rubber bearing platform of the upper shock pad faces vertically downward, and the wedge-shaped small head of the rubber bearing platform of the lower shock pad faces vertically upward. Then press the upper shock pad into the left side of the indoor unit of the air conditioner against the wall. After the wire passes vertically downward through the unobstructed gap, press the lower shock pad into the lower left side of the indoor unit of the air conditioner against the wall. Just press it firmly. Since the height of the upper wedge-shaped rubber bearing platform is sufficient, the shock pads in the same group will not fall off. As the vibration occurs, the system starts to move, slowly bundles the high-strength wire until the high-strength wire is completely taut, and the upper and lower shock pads completely clamp the left side of the indoor unit of the air conditioner. The right side of the indoor unit of the air conditioner is arranged in the same way. After the arrangement is completed, a total of four shock pads in two groups present a four-corner support mode for the indoor unit of the air conditioner. Since the indoor unit of the air conditioner can be regarded as a rigid body, the indoor unit of the air conditioner can no longer move, and the indoor unit of the air conditioner - shock pad - wall is relatively stationary, and the noise disappears.

[0038] Over time, the interior of the indoor air conditioner and its mechanical connectors continue to age, and vibrations gradually begin. At this time, the shock-absorbing gasket continues to move from its original position, producing a converging effect that further jams the indoor air conditioner. Since the self-converging movement and the vibration of the indoor air conditioner are almost simultaneous, it can be concluded that no more noise will occur.

[0039] 2) For floor-standing household appliances, especially washing machines directly placed on the ground.

[0040] Washing machines are often directly placed on the ground. Common forms of contact between washing machines and the ground include four-wheel support and rigid four-corner support. Since the drum inside the drum washing machine needs to move for a long time, it is inevitable that the internal motor shaft will experience frictional fatigue damage, causing the drum inside the washing machine to rotate eccentrically. At this time, the washing machine is driven to shake repeatedly at its location, generating noise.

[0041] For this working condition, first select two shock-absorbing gaskets, fix the wire rope on the wire reel and pass it through the alignment rivet to ensure the correct wire-receiving direction. Place the shock-absorbing gaskets in the same group horizontally so that the ground feet are completely disengaged from the ground, and the wedge-shaped small heads of the rubber bases of the shock-absorbing gaskets on the opposite side are all placed towards the inside of the washing machine. Then press the shock-absorbing gaskets on the opposite side under the supporting part of the washing machine on the opposite side, such as under the pulley or under the machine feet. Since the wedges on the opposite side are placed opposite to each other and the washing machine frame can be regarded as a rigid body, the initial position is fixed. Only with the occurrence of vibration, the system starts to move, slowly retract the wire rope until the high-strength wire is completely taut, and the shock-absorbing gaskets on the opposite side completely lock the corresponding side of the washing machine. The other side of the washing machine is arranged in the same way. After the arrangement is completed, a total of four shock-absorbing gaskets in two groups present a four-corner support mode for the washing machine. Since the washing machine can be regarded as a rigid body, there is no possibility of movement for the washing machine anymore. The washing machine-shock-absorbing gasket-ground is relatively stationary, and the noise disappears.
